Heidi Pratt Preps for �Best Summer of My Life� With Pal, New Show?

Heidi Montag and Spencer Pratt have yet to personally comment on Friday�s announcement (from Montag�s rep) of a breakup.

As some decry the news as another publicity stunt, 23-year-old Montag emerged on Twitter late Friday with a cheerful announcement: �This is going to be the best summer of my life!!!!�

And an old pal � and one-time Hills costar � claims Heidi�s summer plans are already in place.

Jennifer Bunney, who appeared in earlier seasons of The Hills: �Heidi and I are moving into a Malibu beach house this summer.�

The cameras, naturally, will be rolling: Bunney says she and Montag will be filming a new reality show. ��We�re really excited to do girly things and show people who we really are and that we�re really fun, sweet and loyal girls.�

Bunney added that Montag and Pratt, who wed in April 2009, are not �legally� separated.

�But, she is moving in with me. It�s just her being able to have some freedom from marriage and for us to work on our friendship and focus on things we want to focus on.�

The new show will likely deal with Montag�s marital situation, she claimed. ��The show is going to focus on our friendship, getting through things with each other like marriage stuff and boyfriend stuff.�

A rep for Heidi broke the apparent news to TMZ Friday that ��Heidi is looking to move out due to all the fake bad press that Spencer controls�She�s tired of it and is looking for a place and wants to focus on her acting career.�

As reported in Us Weekly, many former friends and family members worried that Montag was isolated and �brainwashed� by Pratt, 26. The couple hired four ex-Marines to guard their L.A. home, spent $400,000 on healing crystals and shut out nearly all of their loved ones � including Heidi�s mom, Darlene Egelhoff.
